Repairing Ceiling Crack Seam
1 Attachment(s)
It's been great reading all the old posts for info as I get ready to renovate our old kitchen (approx 10x9')

One area of concern is a crack that runs the length of the ceiling. The walls and ceiling are plaster and I would like to repair the crack without completely tearing out and drywalling it. Can this be done? The crack is about 2.5/3' from the nearest wall. We plan to add vented range hood along this wall and recessed lights in the ceiling, so we do need to bang it up a bit.

I was thinking I might be able to cut the bad section away, taking it clean to the rafters, over to the closest wall, and leave the rest. Could I drywall this section and have it match up with the plaster thickness? I don't want to end up with a new seam due to my inexperience. :(

Looking forward to hearing your input. Thank you.

Drywall Plaster
Every Ceiling structure on older homes requires individual analysis to determine what is best.

What needs to be determined is if there is any movement or any loose plaster.

If so this needs to be
1 Removed and replaced or

2 Covered with a Fiber mesh (Like The tape for seams only in 3' Rolls) or or/and a fibermesh wire screen used used by masons. Then Set Fast mud.

or 3 Place a Plywood or Solid Framing Backers in the ceiling bays above the cracking areas in the attic if this is accessible. Pre-drill and use lots of adhesive under your backers. :yes: You are not avoiding the mess now!

With one of these methods you may be able to leave the existing plaster. Pre-drilling the plaster with a masonry drill bit is a good idea. Countersinking slightly into the plaster is good to prevent creating new cracks.

:) Be forewarned about the many little lath nails you will run into:(.

Drywall Compound on the first coat was the Set Fast Type correct?:thumbsup:

I said this before am repeating myself because one of the main causes of drywall repairs is using fiber mesh tape with regular drywall compound.

When All is said and done as possible pending on the existing plaster being fairly stable and secure or determined it can be secured you may save the mess and the labor intensive work of demolition and drywall hanging. Perhaps pending on your mud leveling skills as more drywall compound will be needed to blend in the me sch... Your Time Invested and $ for $ may be about the same as starting over at the framing to 1/3 less if I am analyzing your situation correctly comparing it to remodeling projects we have done.

If repairing only the cracking area the total project time may be a lot less... this is including repairs and securing the entire ceiling.

It looks like I'm going to have to have a bit of electrical work done with the new kitchen. Since we already plan to strip one wall the the studs, I'm thinking it might just be a good idea to tear out everything and lay new drywall. Does this seem like good judgement?

This may be best. You will know things are done right.

You can also add can or other lighting if desired much easier.

Wishing You the Best! :thumbup:
